Dear R-helpers, I am helping a SAS user run some analyses in R that she cannot do in SAS and she is complaining about R's peculiar (to her!) way of recoding variables. In particular, she is wondering if there is an R package that allows this kind of SAS recoding: IF TYPE='TRUCK' and count=12 THEN VEHICLES=TRUCK+((CAR+BIKE)/2.2); Thanks for any help or suggestions you might be able

I am just learning to use qplot and can't get the fill/colour to work. Below is the R code for a scatter plot and bar graph. library(ggplot2) x<-c(1,2,3,4,5,6,7) y<-c(1,2,3,2,5,6,3) qplot(x,y, main="Scatter Plot Test", xlab="X Label Test", ylab="Y Label Test", colour="blue")z<-c("van", "van", "van",

I'm trying to prepare some cross tabs, looking at a number of variables against a variable "connector" which has 2 values: "OD Passenger" and " Connector". When I produce a xtabs one way I have observations under "Connector" but against a different variable "Connector" shows all 0 values. What is wrong? I've looked into the na commands

I presume the behavior below (no Connector values in the second table) is because I have na values in my dataframe. How do I get them to list? I found references to na.action and na.pass, but I could not figure out how I could use them with xtabs to list the na as a value. I'm sure there's a simple syntax I need, but it's not obvious to me. > # Weighted Data
